Title: Improvements relating to rubber or rubber-like compositions and articles manufactured therefrom
IPC: C08J5/02
Filed: 1931-11-05
Abstract: Articles are made from a stable mix containing an aqueous dispersion of rubber, fillers, vulcanizing-agents, &c. and at least 0,5 per cent free alkali by rendering the mix unstable and pouring it into a mould before thickening begins, setting, removing the article from the mould, washing, and drying under conditions that allow the contained water to escape.  Preferably the dispersion has a solid content of at least 70 per cent and the stable mix a content of 60 per cent solids. With unconcentrated latex, thickeners, such as gum kayara, or sodium salicylate may be added to prevent fillers from settling.  As setting agents, ammonium chloride, nitrate, carbonate, and acetate are specified, preferably used in combination with other substances such as zinc salts.  Zinc oleate may be used alone.  Alkali earth metal salts, and acetic acid may also be used.  Quick setting is desirable and may be brought about by the use of a quick-setting agent, a large quantity of setting agent, or by heating the moulds.  A mixture of magnesium oxide, sodium triphosphate, and ammonium chloride sets the mix quickly in the cold.  According to an example, 1300 gm. "Revertex," 150 gm. zinc carbonate, 30 gm. sulphur, 10 gm. zinc diethyldithiocarbamate, and 415 ccm. water are mixed with 230 ccm. of a 30 per cent solution of ammonium nitrate, and poured into a mould heated to 80-90 DEG  C.  For cold setting, 380 ccm. of a 71 per cent solution should be used.  The set article is removed from the mould, and washed for 3-4 hours, and is then slowly dried, at a temperature rising to 40 DEG  C.  It is then vulcanized at 70-85 DEG  C. The process is suitable for the manufacture of soles and heels, bathing and other shoes, balls, tiles, mats and the like.  In making soles and heels, metal washers may be placed in the moulds, and the mix poured round them.  Specifications 284,608, 292,964, 326,210, and 330,536, [all in Class 70, Indiarubber &c.], are referred to.

Title: Cooling system for gas turbine blading
IPC: F02C7/12
Filed: 1952-12-05
Abstract: 736,029. Gas turbine plant. LAGELBAUER, E. Dec. 5, 1952, No. 30970/52. Class 110 (3). A gas turbine plant comprising a high-pressure turbine driving directly separate high-pressure and low-pressure compressors in which the high-pressure compressor discharges through a combustion chamber to nozzles subtending over a segment of the blades of the highpressure turbine, has compressed air taken from the low-pressure compressor led to the remaining segment of the high-pressure turbine blades and the mixture of combustion gases and cooling air from the high-pressure turbine exhaust led to a lowpressure turbine. The high-pressure turbine 10 drives a low-pressure compressor 11 and a highpressure compressor 12 between which is arranged an intercooler 13. The air leaving the high-pressure compressor 12 is heated in a heat exchanger 15 by the exhaust gases and then further heated in a combustion chamber 16. The combustion gases from the chamber 16 pass through a nozzle 18 on to a segment 34 of the turbine blades 19. The exhaust gases from the turbine 10 pass to a low-pressure turbine 20 driving a load 21. Some of the exhaust gases may pass through a control valve 26 to a turbine 23 driving another low-pressure compressor 24. The turbine 23 may be omitted and the compressor 24 driven by the turbine 20. The control valve 26 may, in an emergency, divert the gases direct to atmosphere through conduit 27. The air from the the low-pressure compressors 11, 24 is divided by a control valve 28, part of this air passes through the intercooler 13 to the high-pressure compressor and part passes through the conduit 65 to the segment 31, Fig. 3, of the turbine blades. The compressed cooling air is mixed with the combustion gases and passes therewith through the duct 63 to the lowpressure turbine 20. The compressed cooling air passes over the blades 19 in a radial direction. In a modification, the cooling air passes over the blades in an axial direction. In this arrangement, an axial flow compressor stage is mounted on the compressor shaft so that it discharges through fixed vanes on to the turbine blades.

Title: Devices for dispensing liquids into flowing streams of gases
Inventor: DILLON WENDELL M
IPC: F16N7/34
Filed: 1961-08-29
Abstract: 945,048. Spray producers. WATTS REGULATOR CO. Aug. 29, 1961, No. 31079/61. Heading B2F. [Also in Division F2] A device for entraining a liquid into a gas stream comprises a Venturi or like constriction, in a gas inlet-outlet passage, the liquid being forced into the constriction from a reservoir by the pressure of the gas communicated to the reservoir from a point remote from the throat of the constriction, and being entrained by thegas flowing through the constriction, and a by-pass passage around the constriction with a valve therein which opens when the flow of gas at the outlet connection exceeds a predetermined amount. The application of the invention to a lubricator for pneumatic tools is described wherein the lubricator has a gas flow passageway 48<SP>1</SP> (Figs. 1, 2) with throat section 50<SP>1</SP> and a passage 60<SP>1</SP> having apertures 64 which serves to communicate the static gas pressure from a point downstream of the throat to a gas space 132 above the liquid in reservoir 124. The pressure differential between the throat 50<SP>1</SP> and gas space 132 causes liquid to flow up a dip tube 72<SP>1</SP>, past non return ball valve 78<SP>1</SP>, along passage 76 in reservoir head 14, into a central bore of an annular boss 80 having screwdriver-adjustable valve members 84<SP>1</SP>, 88, down discharge tube 94 to chamber 108, from whence it is dripped through bevel edged dispensing tube 104<SP>1</SP> to the throat 50<SP>1</SP> where it is atomized and entrained in the gas flow. If atomization is incomplete large size particles are collected on annular abutment 66<SP>1</SP> and scavenged down passage 60<SP>1</SP> to the reservoir. The by-pass passage includes a valve controlled passage 134, the space between a baffle plate 130 and the lubricant, and the passage 60<SP>1</SP>. The valve acts to normally close passage 134 and open it when the demand for gas exceeds a predetermined amount. In a further embodiment (Fig. 3, not shown) there is also a gas passageway which communicates the incoming upstream gas pressure to the gas space above the lubricant whether or not the valve is closed.

Title: Improvements in or relating to liquid detergent compositions
IPC: C11D3/22
Filed: 1955-10-31
Abstract: A liquid detergent composition in the form of a stable colloidal dispersion or coacervate comprises a synthetic surface-active agent, a complex phosphate salt, and a carboxymethyl cellulose material having a degree of substitution of at least 1.0.  The surface-active agent, which may comprise from 5-30 per cent of the composition, more preferably 10-20 per cent and most desirably about 15 per cent, may suitably be an alkyl aryl sulphonate or ethylene oxide condensates with tall oil fatty acids, with alkyl phenols, with coconut oil fatty acids or with propylene oxide or be mixtures of such reactants.  The concentration of the complex phosphates, preferably in the form of the sodium or potassium salts, and especially the latter, may be varied within a considerable range, but a concentration of 20-35 per cent, preferably about 28 per cent, produces the most desirable results.  The term complex phosphates is here to be taken to include pyro-, meta-, and polyphosphates, but the best results are obtained with the tripolyphosphates.  The carboxymethyl cellulose material is generally employed in the form of the sodium salt and has a degree of substitution usually of 1.0-2.0, preferably 1.1-1.4 and most desirably of about 1.2, and is used in concentrations of 0.6-5.0 per cent, preferably 1.25 per cent.  The dispersion is suitably made up by dissolving the carboxymethyl cellulose material in water, adding the phosphate either in solution or as a solid, and finally adding the surface-active material either with or without such additives as perfumes, bleaches, and optical brighteners, and then finally passing the mixture through a homogenizer to produce the colloidally-dispersed detergent solution.
